Component Tests
Pressure Test
A WARNING:When releasing the cooling
system pressure, cover the coolant
expansion tank cap with a thick cloth to
- prevent the possibility of coolant scalding.
Failure to follow this instruction may result
in personal injury.
N0TE:lf the coolant expansion tank cap is rotated
counterclockwise by 1 12 a full turn, the pressurized
coolant will be vented to the underside of the
coolant expansion tank cap.
1. Remove the coolant expansion tank cap.
2. Install the special tools 303-396 and 303-396-01
to the coolant expansion tank.
3. Pressurize the system to the coolant expansion
tank cap release pressure.

303-03B-15 Engine Cooling - 2.OL Duratec-HE (M14) 303-03B-15
DIAGNOSIS AND TESTING
A CAUTI0N:lf the ECT sensor output reaches
the
120°C default line under normal cooling
system pressure, internal damage may be
caused to the engine and a diagnostic
trouble code (DTC) will be set in the PCM.
The test should be stopped and the cause
located and corrected. If the cooling
system does not pressurize, the coolant
will boil at
1 OO°C which may also damage
the engine. CARRY
OUT the Coolant
Expansion Tank Cap Pressure Test
Component Test in this section.
If the WDS only allows the ECT sensor to be
displayed in volts, refer to the following table for
corresponding Celsius values:
The CHT sensor output is useful to examine the
cylinder head temperature rise during the warm-up
cycle and later during the normal light throttle cruise
test. This sensor output may vary between vehicles
with manual transmission and vehicles with automatic transmission and should be used for
reference only.

0.60
0.46
0.35 0.27
The LOAD display is used for reference as it is
necessary to maintain a stable load line during the
test. It is necessary to carry out the test under
normal light throttle cruise driving conditions and
average loads, typically 40% to 70% of the load
value.

The VSS output is used for reference but can help
to identify misfires and sensors which fail during
the warm-up cycle.
The RPM display indicates the engine speed and
can be compared with the DSRPM.
The DSRPM is the desired or calculated idle speed
which the PCM commands the engine to reach. If
the thermostat opens too early (before the correct
opening temperature has been reached), the
engine will not reach this value. When
using the WDS in data logger mode, the
signals recorded should remain within the
DEFAULT values set by the WDS.
3m AWARNING:M~~~ sure that the WDS is
placed in the vehicle so that it does not
interfere with the safe operation of the
vehicle. Do not place the WDS in the
deployment path of any air bag. Failure to
follow these instructions may result in personal injury.
N0TE:The road test is best carried out with the
aid of another technician in the vehicle to enable
the vehicle to be driven safely while the sensor
outputs are monitored within datalogger. If there
is only one technician available, the WDS can be
set up (using the
recordlcapture mode camera
icon) before leaving the workshop to record a 16
km (1 0 mile) test.
N0TE:The results from the test are more
conclusive if the engine is cold when the test is
started.
Carry out a road test.
REFER to:
RoadIRoller Testing (1 00-00 General
Information, Description and Operation).
4. Drive the vehicle at a constant throttle opening
and set speed until the ECT value settles into
a shallow rise and fall signal, close to a straight
line. This indicates that the thermostat is
functioning correctly.
N0TE:Some thermostats indicate the
temperature(s) in Celsius and Fahrenheit.
The graphic below shows the location and an
example of the opening temperature
(88OC) and
fully open temperature (1
02OC) of a thermostat.
The graphic below shows an alternative method used to show the opening temperature
(88OC) and
fully open temperature
(112OC) of a thermostat.

The intake manifold for both Ethanol
E85 and
standard unleaded fueled vehicles is the same

Built into the intake manifold, are the
IMRC throttle
plates and IMT swirl plates.
Under low demand throttle conditions, the air
charge is delivered to the cylinder head intake ports
through the primary air intake chambers. The clean
flow of the air charge is disturbed by the IMT swirl
plates to assist in the mixing of the air fuel mixture
at the fuel injectors.
